Format the cuDF Parquet read script with ruff

`uvx ruff format --check .` failed the Python (lint) job on the `--iterations`
argument: the call was wrapped across three lines, but at 91 characters it fits
inside the repository's 120-character limit, so ruff collapses it to one line.

Ran `uvx ruff format` rather than hand-editing so the result matches CI byte for
byte. `uvx ruff format --check .` and `uvx ruff check .` both pass locally now.
